[[howto.nosql]]
== NoSQL
Spring Boot offers a number of starters that support NoSQL technologies.
This section answers questions that arise from using NoSQL with Spring Boot.



[[howto.nosql.jedis-instead-of-lettuce]]
=== Use Jedis Instead of Lettuce
By default, the Spring Boot starter (`spring-boot-starter-data-redis`) uses https://github.com/lettuce-io/lettuce-core/[Lettuce].
You need to exclude that dependency and include the https://github.com/xetorthio/jedis/[Jedis] one instead.
Spring Boot manages both of these dependencies, allowing you to switch to Jedis without specifying a version.

The following example shows how to accomplish this in Maven:

[source,xml,indent=0,subs="verbatim"]
----
	<dependency>
		<groupId>org.springframework.boot</groupId>
		<artifactId>spring-boot-starter-data-redis</artifactId>
		<exclusions>
			<exclusion>
				<groupId>io.lettuce</groupId>
				<artifactId>lettuce-core</artifactId>
			</exclusion>
		</exclusions>
	</dependency>
	<dependency>
		<groupId>redis.clients</groupId>
		<artifactId>jedis</artifactId>
	</dependency>
----

The following example shows how to accomplish this in Gradle:

[source,gradle,indent=0,subs="verbatim"]
----
	dependencies {
		implementation('org.springframework.boot:spring-boot-starter-data-redis') {
		    exclude group: 'io.lettuce', module: 'lettuce-core'
		}
		implementation 'redis.clients:jedis'
		// ...
	}
